The influence of libraries on the phenomenon of witch hunting in Europe is shown based on a review of historical sources about libraries on the phenomenon of witch hunting in Europe. Based on a review of historical sources about libraries dedicated to the phenomenon of witch hunting in Europe, the first attempt has been made to study the direct impact of libraries on the phenomenon of witch hunting in Europe. In this study, comparative historical and descriptive approaches of the above historical sources were used. Using these methods of processing archival documents, information on the influence of European libraries on the phenomenon of witch hunts is revealed on the basis of available sources. A review of some historical sources is proposed in order to clarify the influence of European libraries on the phenomenon of witch hunts in the context of certain chronological frameworks and socio-political conditions. The object of the study is the literature and libraries of Europe in transition. A problem-chronological method was used to study the influence of libraries on the phenomenon of witch hunts. The basis of the research consists of the main principles of historical science. Historicism and scientific research make it possible to assume the main influence of European libraries on the phenomenon of witch hunts according to the chronology of events against the background of the specified historical period of time. At the same time, the array of historical materials found and currently published is strictly taken into account. General scientific and special historical methods constitute the methodology of the presented research.
